SOLAR wATER HEAT ERr SPECIFICATION forming part of Letters Patent No. 629,122, dated uly 18, 1899 Application filed March 20,1899- serlalliu. 709,782. (No model.)

In all witgm it may concern.- I Be it known that 1, CHARLES A; DAVIS, a citizen of the United States, residing at Pasadone, in the county of Los Angeles and State of California, have inventedcertain newand usefullmprovementsinSolarW'ater-Ileaters;

and'I do declare the following tube a full, I clear, and exact description of the invention,

This invention relates to certain new and useful improvements in solar heaters; and it relates more specifically to the provision of an apparatus of this character which is designed especially for heating water; and to this end theinvention consists in the provision of receptacles contained within a suitable inclosure and preferably surrounded by a heat-retaining material-such, for instance, as sawdust-and one of the inner walls of the receptacle being provided with a series of reflectors arranged upon the arc of a circle, whereby the rays of thesun may be reflected at all hours, a glass cover to the receptacle being provided through which the rays pass. 3O

to the reflectors. I

The invention has for its further object the provision of means for equally distributing the cold water as it enters the receptacle, and

also in the means provided for preventing any backfiow after the water enters the receptacle to be acted upon by the rays of the sun.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- I Figure 1 is a sectional'view taken through the heater. Fig. 2 is a plan view with the top or covervremoved in order to better illustrate the construction contained within the casing. Fig. 3 is a perspective view of the heater, a

I portion being shown as broken away.

Reference now being had to the details of the drawings by letter, A designates the casing, which may be of any suitable material. The front edge of the casing is somewhat shorter than the rear edge, as shown.

Contained within the casing are water-receptacles B, which may be of any suitable or desired size or number,.which receptacles I have shown in the drawings as of cylindrical form, and they are designed, preferably, to be embedded in a suitable heat-retaining material, as sawdust or its equivalent, (represented by the letter C.) It is my purpose to partially surround the receptacles with this heat retaining material, leaving the face of the receptacle adjacent to the reflectors free from the material in order that the reflected heat will not lose its energy until it reaches the wall of the receptacle containing the water to be heated. I

D designates the inlet-pipe, which enters theouter side of the two cylindrical receptaclcs near its lower end, as shown, and leading from the upper end of the same receptacle is the upperend of the pipe E, which communicates between the two cylindrical receptacles, the lower end of the said connecting-pipe entering the second receptacle at a point-near'its lower end and serves as a means for causing the heated water to pass from the first to the second receptacle. This supply-pipe extends into the second receptacle and is perforated in the first receptacle, distributing the water at the bottom, as

shown. Leading from the'upper portion of the second receptacle is an outlet-pipe 0, through which the heated water may pass to any desired location.

A check-valve H pipe, outside of the first receptacle, which serves toprevent the backflow of the water that enters the receptacles. the inlet-pipe which extends within the receptacle is provided with a series of perfor. tions K K, while the inner end of the pipe is pluggedup or closed-thus causing the sup ply of water to be forced through theperforations and evenly distributed into the receptacle in a downward direction. l

Arranged about one wall of the casing is a series of reflectors M of any desired size or is located in the inlet- That portion of,

water to belheated. The cover N, which is of glass, may be held to the casing inany suitable manner.

in the receptacles,it is m'ypurposeto surround the case containing the water-receptacles with i an outer casing A, between which and the inner casing,on the sides and bottom, is a slight space, as shown in the drawings, and

-- when the heatingapparatns is equipped for use it is my purpose to incline the'casing" at.

an angle'and to make the necessary connections with storage-receptacles.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is- Y A solanheater, comprising in combination with the double-walled box mounted at an inclination, of a heat-retaining material therein, the water-receptacles supported by and partly embedded in said heat-retaining material, suitable connections between said receptacles, theiuclined reflector's'in said box,

and the double glass cover, with-space intervening between same, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses;
